y IMPROVED BOOT AND SHOE-HEEL.

TO ALL WHOM IT MAY CONCER'N Beit known that we, Cnnisrornnn Dran, dr., and Ennis Dunne, of Stoughton, in the county of Norfolk, and State of IvInssachusetts,-have invented a new and useful improvement in Boot and Shoelleels; and we do hereby declare the following to be a clear and exact description ofthe nature thereof, suilicient to enable others skilled in. the art to which it appertains to fully understand and use the same, reference being` had tothe accom'- panying drawings, making part of this'speciiication, in which- Figure l is a top View.

Figure 2 is a front view.

Figure 4 is a central Vertical longitudinal section. i

Similar letters of reference indicate corresponding-parts in the several figures.

Our invention consists in constructing the heel of a boot or shoe of wrought metal, whereby chcapness and Strength are combined. Also, invthepeculiar mode of locking the endsofthe metal forming the heel, whereby a. perfect joint is formed, and which cannot be displaced by strains or' blows in any direction. Also, in a metal tread-plate to be applied tc the heel. Also, in the mode oi' lsecuring the heel and its tread-plate to theboot or shoe;` all as will be hereinafter more fully described.

In the drawings, A represents the-body of the heel, constructed according to our plan,'to be made of wrought metal of certain thickness and'ot` proper shape, being cut by suitable machinery. The ends of the-plate consti-V tuting the body of the heel are united together in front by a. lock or groove joint, B. Both ends are swagcd or bent into hooks which, fit into each other. It will be seen. that all pressure on the heel, and the expansion thereby, will lock the ends tighter. In order to prevent the lock from becoming undone, one of the hooked ends c of the metal plate is bent inwardly, as at @which will leave a shoulder, AL, against which the curve of the hook of the other end c2 shall bear. The front of the heel will therefore present an almost unbroken sur face. It is evident that if any strain is directed inwardly against the sides of the heel,f'the shoulder 71 will receive the strain or shock, and prevent the hooked end Z1 from being forced out of place.

We thus present a simple means of securing the ends of the plate, and form a heel which is entirely practical.

rIhe advantages of constructing the heel from wrought metal are that it can be easily and quickly cut, the ends readily united, lightness and strength are combined, the nature of the metal gives the proper rigidity, as also elasticity, besides cheapness and utility. Cast iron has not the above advantages, and we therefore claim superiority over it. i

C represents the tread-plate of the heel, which is to' be cast of s utlcient thickness and of size to conform to the shape ofthe heel, and fitting therein bya shoulder ruiming around the upper side. A'notch is also made on the upper front edge, to allow the bottom of the lock-joint to fit therein. The lower face of the treadplate may be partly or entirely corrugated. In the former case a ridge or ilangc maybc made to extend around the edge. The centre of this plate isperforated, or open and countersunk, to receive a screw, D, whose head will snugly fit therein, and be flush with the lower face of the plate. The plate may have more than one perforation to receive a corresponding number of screws. The screw or screws extend through the hollow of the' heel into lugs or nuts E, which are secured to the shank F, and scarcely increase the weight of the heel. It is evi'- dent that when the screw or screws D are turned into the nuts E, the tread-plate C is brought rmly against the heel A, and then the heel snugly against the corresponding part of the boot or shoe. We thus dispense with any other mode of fastening.

It is unnecessary to sew, peg, or nail the heel to the leather of the shoe, the screw' or screws D accomplish; ing all that is necessary for retaining it in place.

Although there isyan objection to metal from whichwe make the complete heel, we overcome the objection by the simplicity of construction. Our heel is almost entirely hollow, the screws being the only parts within it. There is no riveting or soldering, and scarcely any opportunity for the parts becoming undone. The screws and lugs or nuts, es repplicd tol the metallic shank for holding the heel in piece, are the snbjectmatter of 'a u patent granted to us of dote August G, 1867, :is 'improvements thereon.

Having thus described our invention, what we elaiin as new, and desire to secure by Letters Patent, is

A heel having the following Characteristics: A body, A, constructed of wrought mete', a enst-metal tread, C, en d screws D, adapted to be applied te a. separate shank, F, havinglug or nut E, whereby the parts are held together independently of any other festenings, as herein described.

To the above we have signed our names this 4th day of September, 1867.--
